Sorry for late reply... I had some problem while sending .. but it seems i am able to send messages of size 256 kb also. but the surprising thing is while consuming some 10 000 messages the memory shoot up is more, and finally out of memory. is there any memory leak is happening from JBM side while consuming ?? if try to consume 512 kb from persistance data base , consuming only the memory shoot up very much . dont know what to do ?? and also if i close consumer five , six time, it simply stuck while getting the connection? --Thanks View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4150922#...
